Do Gary Neville and Jamie Carragher have what it takes to be professional referees?
The pundits were put through their paces by Premier League officials for a special programme to be shown on Sunday on Sky Sports 1 at 7pm called The Referees - Onside with Carragher & Neville.
From brandishing the cards to running the line to even taking a fitness test, the Monday Night Football duo were tested on every aspect of being a referee.
The former England internationals also sat down with a number of the Premier League's top officials to give an insight into what it takes to referee in England's top flight, analysing some key decisions from the season so far along the way.
And there's also a reenactment of Mike Dean's famous "celebration" after playing an advantage which allowed Tottenham to score in their 3-1 win over Aston Villa last season!
How did Neville and Carragher get on? This one line tells the story with former Liverpool defender Carragher saying to referee Neil Swarbrick: "I will never ever criticise you ever again!"
